FORGING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 557,922, dated April'7, 1896.

Application filed May 27, 1890. $erial No. 353,309. (No model.)

To all'whom it may concern.-

Be it known that 1, WILLIAM R. WEBSTER,

of Philadelphia, county of Philadelphia, State of Pennsylvania, haveinvented a certain new and useful Improved Forging-Machine, of which thefollowing is a true and accurate description, reference being had to thedrawings, which form a part of this specification.

My invention relates to forging-machines, and my improved apparatus ispeculiarly, though not solely, adapted for use in the manufacture ofeyebars. I

My machine is intended to be used in connection with forgings' which arebrought approximately to form in another apparatus or by other means,said forgings being then removed to my improved machine, whereby theyare subjected to the last perfecting operation and made to assume theprecise shape desired.

The nature of my improvement will be best understood as described inconnection with the drawings, in which they are illustrated, and thenovel features which I desire to protect by Letters Patent arehereinafter clearly set out in the claims.

In the drawings, Figure 1 is a side elevation of my improved apparatus;Fig. 2, a plan View thereof; Fig. 3, a vertical central section; Fig.4., a front elevation; Fig. 5, a plan of the base-plate; Figs. 6 and 7,views of peculiar rolls adapted for use in connection with my apparatus;Fig. 8, a side elevation of a modified machine embodying myimprovements; Fig. 9, a similar view partly in section; Fig. 10, a planview of the die used in connection with the machine shown in Figs. 8 and9. Fig. 11 is an elevation of the machine shown in Figs. 8 and 9, andFig. 12 is a view showing a clutch used in said machine.

A is the base-plate, which, as shown in Fig.

3, is provided with a central projection B,

upon a shouldered portion B of which the base-plate O of the housing ispivoted, while a projection B serves to hold the plate I, in which isformed the die.

0, as already stated, is the main or base plate of the housing. It ispivoted on the plate 0 sustains a cylinder D, in which is secured thepiston D and the piston-rod D 13 is a flange of the plate A, on whichthe end 0 of the plate 0 can restas it turns on the pivotB.

E is a plate, which is secured to the dieplate I by means of rods F F,having threaded ends f.

G is a housing or support for rolls H 11, said housing being secured 011the end of the piston-rod D and the rolls II II resting, re spectively,against the plate E and against the die in the plate I, or the workresting in the die. The plate I is provided on its under side with acavity 1,, which fits over the projection B and has formed in it adie-cavity i.

J J are cheek-pieces fitting in the die-cavity and forming the walls ofthe die proper. These are conveniently made adjustable, so as to adaptthe die-cavity for the manufacture of eyebars or other articles ofdifferent s1zes.

K represents the work placed in the cavity of the die.

L L, &c. are wheels screwing on the threaded ends f of the rods F F.These wheels are gear-wheels and en gage with the central gearwheel M,which is turned by a hand-wheel N or in any other convenient way, so asto press the plate E down or permit it to rise.

The eyebar is placed in the die-cavity, and the housing G, carrying withit the cylinder and the rolls H H, is then moved on the pivot 13 untilthe rolls are in position to roll the eyebar in the direction required.Steam or water is then admitted to the cylinder, and the housing orbearing G, carrying the rolls H H, caused to move backward and forwardover the work, the roll II acting directly upon the face of the eyebar,and at the same time the plate E is pressed gradually downward, theresult being that the eyebar-head is rolled out to fill and fit the die.If it is desired to roll it in another direction, the housing G isturned and the same operation continued. In this way the rolling actioncan be both transverse and longitudinal or can take place in a lineintermediate between them and the eyebar can readily be made to fill thecavity of the die.

It is desirable in some cases that the face of the roll H, which actsupon the head of the eyebar, should be provided with projections, suchas h and h, Figs. 6 and 7, these projections corresponding with theoutline of the die-cavity and fitting into the said cavity.

Referring next to the modified form of the machine shown in Figs. 8, 9,and 11, the cylinder D is supported upon a base 0, which in turn ispivoted to the base-plate A at 0. The die I rests on top (marked d) ofthe cylinder D, and is held stationary by the upright brace R. AU-shaped forging or casting P P P is formed so as pass above and belowthe cylinder D. The pressure-roll H is secured in its upper arm P, so asto pass over the face of the die, and rolls 1-1 are secured to its lowerarm, so as to press upward against projecting flanges d of the cylinderI). The U shaped forging P is attached to the piston-rod D as shown, andis given a reciprocatin g motion by the action of the piston in thecylinder D. The roll H is pressed down by means of screw-rods A whichare actuated by gear-wheels L, which in turn are actuated by a commongear M, attached to the spindle N, which spindle can be turned either bythe hand-wheel N or by a chain U passing over a sprocket -wheel M and asprocket-wheel T, which wheel T is attached to a frame S, which moveswith the U shaped casting P, and is supported and guided by a standardQ, which is attached to the pivoted support 0, so as to turn with it. qq indicate angle-irons serving to support frame S. By means of thischain the reciprocation of the support S in the standard Q can readilybe made to effect an automatic or other feed of the roll H. V indicatesa clutch which can be moved from side to side on its pivot 10, so as toengage a projection w or 10 with the chain. This modified machine, aswill be seen, has the same capacity for changing the angular position ofthe pressure-roll as has the machine first described. The die I remainsstationary, being held by the standard R, and the cylinder D, togetherwith the U- shaped piece P, the standard Q, and the parts connectedtherewith, can be rotated to any desired angular position with respectto the die.

Having now described my invention what I claim as new, and desire toprotect by Letters Patent, is

1. In a forging-machine the combination of a die with a pressure-rollarranged to reciprocate over the face of the die and means for changingits relative position with respect to said die, all substantially asspecified and so that the work in the die can be rolled in differentdirections.

2. In aforging-machine, the combination of a stationary die adapted tocontain the work, a pressure-roll arranged to reciprocate over the faceof the die, bearings for said roll pivoted so as to turn it to variousangular positions on the die, and feeding mechanism arranged to depressand elevate the pressureroll, all substantially as and for the purposespecified.

In a forging-machine, the combination of a stationary die, apressure-roll arranged to act on the face of the die, a cylinder andpiston arranged to give the roll a reciprocating movement, a pivotedhousing arranged to support the cylinder and pressure-roll, and meansfor feeding the roll to and from the die.
